MARINE SALVAGING DEVICE Original Filed March 29, 1928 Patented Feb. 11, 1930 UNITED STA ANDREW IVERSON, OF SEATTLE, WASHINGTON MARINE SALVAGING DEVICE Appliieationled March 29, 1928, Serial No. 265,574. Renewed November 18, 1929.

Myl invention relates to marine salvaging devices and the principal objects of the invention are to provide means whereby a buoy may be released from a submerged vessel, and,`

` by means of hose together with extension wires from the broadcasting apparatus woundupon a windlass and connected to said buoy, communication by wireless together with means for supplying fresh air vand means for direct communication with the crew of the submerged vessel may be established.

With the above and other objects in view which will appear as the description proceeds, the invention consists of the novel construction, adaptation, combination and arrange- `ment of parts hereinafter described and claimed. These objects are accomplished by devices illustrated in the accompanying drawings, wherein:

Figure 1 is a view in longitudinal vertical section of a fragmentary portion of a submarine showing my device installed therein;

Fig. 2 is a view in transverse vertical section of the same;

Fig.` 3 is a detail view in longitudinal vertical section of the buoy and showing the broadcasting aerial in the raised position in dotted lines; and u Fig. 4 is a view showing the practical application of my device in connection with a sunken submarine.

Referring to the drawings throughout which like reference numerals designate like parts, the numeral 5 indicates a submarine having a compartment 6 in the nature of a well secured to the underside of its deck with an opening through said deck equal to and flush with the interior of the compartment A slidable door 7 is adapted to close said opening by means of an integral or fixed rack 8 in mesh with a toothed wheel 9.l The shaft 10 of said wheel is sealed through the deck of said submarine by a stuffing boX 11 and is provided with an annular handle 12 whereby the door may be opened and closed from the interior of the vessel as will be understood. A grooved coaming 13 serves as a guide for the door and also makes the compartment substantially watertight. A

drain cock 141 may be disposed at the bottom of said compartment to drain off the water when necessary.

Mounted within the lower portion of the compartment 6 is a hollow windlass 15 with its solid stub shaft 16 sealed through one side thereof by means of a stuffing boX 17 and its hollow stub shaft 18 sealed through the opposite side by a stuiing box 19. The end of the shaft 16 is provided with a wheel or pulley 20 having a handle 21 thereon whereby the windlass may be either mechanically Y or manually operated as desired.

Wound upon the windless 15 is a double hose 22 which is sealed through said windlass at 23 and passes out through the hollow stub shaft 18 with its threaded ends 24 projecting into the interior of the submarine whereby other hose may be connected therewith. It will be understood that said hose is double for the purpose of pumping fresh air into the submarine through one part thereof and exhausting the foul airV from theV submarine through the other part as more fully hereinafter set forth. Extension wires -25 from the wireless sending or broadcasting apparatus are wound upon said hose for reasons also more fully hereinafter specified.

A buoy 26 arranged to fit snugly and loosely within the compartment 6 is supported in the upper portion thereofuby brackets 27. Said buoy is air tight and has a conduit tube 28 passing through its center. A flanged recess 29 is povided in the upper portion of the buoy and a suitable weight 30 provided within the bottom of the buoy is adapted to always retain said buoy when afloat in such position that said recess will be on top and said conduit will be disposed in a normally vertical position.

A pair of foldable arms 31 having their ends pivotally secured at 32within the recess 29 are adapted to serve as poles for the antennae 33 of the wireless system. When in the folded position said arms are completely housed within said recess and their ends 34 are flush with the end walls of the buoy 26 and thus serve as shoulders in abutment with the interior walls of the compartment 6 to retain them in the folded position as clearly shown in Fig. 3 of the drawings. Springs are adapted to cause said arms to assume a vertical position when the buoy is released from said compartment with their ends 34: in abutment with the bottom of said recess 29.

The inner ends of the double hose 22 may be secured together by a clamp or other means as shown at 36 with a cable or other line 37 secured to said clamp and extending to the buoy 26. Said cable passes through the'con duit 28 of said buoy to the antennae 33. The extension wires 25 are coiledaround said hose and cable throughout their lengths and are connected with said antennae in the usual manner as shown in Figs. 3 and i of the drawings.

For the purpose of relieving the aerial from strains I have provided a stop 38 which may be a'ball fastened around the line 37 below the buoy 26 and a similar stop 39 secured to said line above the buoy. vWhen the arms 31 are in the raised position the stop 38 will be in Contact with the bottom end of the conduit tube 28, and when said arms are in the folded position the stop 39 will be in engagement with the top end of said tube thus relieving the wireless connections from all strains in both directions.

In preparing my device for use the buoy 26 is placed in the compartment 6 with its ends resting on the bracket supports 27 and with its arms 3l folded into the recess 29. The door 7 is then securely closed and the slack of the line 37 is taken in on the windlass 15. In so far as my apparatus is concerned the submarine is now ready to submerge. If the submarine should become disabled and refuse to rise to the surface of the Vwater whereby the lives of its crew are endangered the door 7 is opened by turning the handle l2. As the water enters the compartment said buoy will rise to the surface as shown in Fig. 4:.

Upon rising to the surface the buoy 26 will, of course, carry the line 37 and wires 25 up wardly and the springs 35 willI cause the arms 3l to assume an uprightposition immediately the buoy is released from its Compartment. Vireless communication now being established a call may be sent out for assistance. The buoy will serve to locate the position of the submerged vessel and the rescue party lnay haul up the double hose 22 and pump fresh air into the sunken submarine through one hose while the foul air escapes through the other hose. They may also communicate directly with the submarine crew by using the hose as a speaking tube. A diver may use the hose as a guide in his descent to the vessel and other advantages will doubtless suggest themselves in a consideration Vof the utility of my device.

Having thus described my invention, it being understood that minor changes may be resorted to in the structural details without departing from its scope and spirit, what I claim and desire to secure by Letters Patent of the United States is:

The combination with a submarine of a marine salvaging device comprising a com partrnent, a windlass within the compartment having watertight connections for its bearings through the walls thereof, a buoy, a double hose and line for the windlass connected to the buoy, said hose having a watertight connection through the windlass to the interior of the submarine7 broadcasting wires extending along the hose and line from the interior of the submarine to the buoy, a foldable aerial for the buoy connected with said broadcasting wires housed within a recess in said buoy, means for retaining said aerial in a folded position when the buoy is within its compartment, spring and stop ,means for causing said aerial to assume an upright po- I sition when the buoy is released, a door for the compartment, and means within the submarine for opening the door and releasing the buoy to flotation when the submarine is submerged.

In witness whereof, I hereunto subscribe my name this 1st day of March, A. D. 1928.
